Florida is revisiting this as I said upthread. They have changed the wording of the code for plate penetrations fron "draftstopping" to 'fireblocking" which will eliminate foam in wood construction.
This is still not the same as "firestopping".
I can see that this will be another year of trying to decide what 67 counties and 500 cities will consider appropriate. They seem to be as interested in smoke as they are fire. I suppose red caulk will always work but it is probably more than you need.
